Storage rack system for Hobby paints

This is a paint rack/storage system for hobby and miniature paints. The paint bottles are held in interchangable trays that can be placed on the shelves. I created a few variations: parts tagged with "26mm" fit paint bottles of 26mm and smaller.  This includes Scale75, Vallejo, Army Painter, Warcolours, OLD monument/pro-acryl, Reaper, Turbodork, etc (nominal size of bottle holders is 26.5mm).  Holders hold 8 paints per tray. Parts tagged "GW" fit the wider pots from Games Workshop, P3, cote d'arms, NEW monument/pro-acryl and others. (nominal size is 33mm).  7 pots fit in each tray. The holder tagged as "GW-26" is sized to fit in the shelf intended for the GW sized paints, but holds 8 26mm pots instead of 7 33mm. The shelves come in 4 and 5 tray sizes.  All will fit within the build plate of a prusa mk2/3 (the largest size will need to have the skirt disabled on a prusa mk2/3) Parts pictured were printed on Prusa mk3, at 10-15% infill (gyroid), 0.20mm layers, using a mix of hatch
